6 claims. (or 229-39) The present invention relates to cartons and, closing flaps at their opposite sides, these being more specifically, to cartons made from a single aps of the usual nature, 9, 10, 11 and 12, to form blank of foldable material and in which all of the a bottom closure for the carton, and the other coacting elements are pre-cut and scored, parflaps being 5, 6, 7 and 8 to form the retuck clo- 5 tially connected and shipped iiat to the consumer sure for the top reclosure seal of the carton, all 5 'for nal erection and assembly. of the flaps being scored off the panels by the The important feature of the present strucscore lines 18 to 25 inclusive, these lines being ture is in the end construction, whereby the carshown dotted. ton, when erected and sealed, may be ruptured When the carton blanks are shipped to the l along pre-cut lines to open, and the ruptured porconsumer, the glue aps 13 are attached, by glue, 10 tion be used as a retuck cover flap to temporarily to the inner face of the exposed edge of the close the carton. panels 1, and the cartons are folded flat, into While I have for the sake of clearness and in bundles, for shipment. order to disclose my invention so that the same When the consumer uses the carton, he erects l can be readily understood, described in general the blank into a carton formation, glues the four 15 terms and illustrated specific devices and arbottom naps 9 to 12, together in the usual manrangements, I desire to have it understood that ner to form a permanent bottom closure. this invention is not limited to the specic form The carton is then filled, and the top cover disclosed but may be embodied in other ways that naps are then operated as follows:

It is be- 5 is Closed in on flaps 6 and 8, and, nally the lieved that this invention is broadly new and it retuck nap 7, with glue on its inside face, is is desired to claim it as such so that all such closed down over flap 5 and the package` is thus changes as come within the scope of the appended sealed, as shown in Figs. 2 and 3.

body fOrming panels 1, 2,3 and 4, and a glue and thus an effective sealing of the carton top 50 ap 13, all scored from one another in the order is effected. above described, by score lines 14 to 17 inclusive, After the top is sealed, to open, it is only necesshown dotted. sary to press downwardly upon the flap 7, as

The rear and front walls orpanels 1, 3 and the 'indicated by the arrow P in Fig. 5, rupturing the lateral panels 2, 4 inclusive have separate, scored flap part B away from the tongue section T, thus 55 2 breaking the weakened line 27-28-28 as at A, Fig. 4.

Then the top flaps 5 to 8 inclusive may Abe lifted to afford access to the carton contents.

To reclose the carton, as a temporary seal, the flaps 6 and 8 are first closed, flap 5 is then closed down over naps 6 and 8, and then the tongue T of top flap 'I is inserted into the slit 26 of iiap 5. as in Figs. '1 and 8.

As will be noted in Fig. 6, when the sealing top naps 5 and '7 are ruptured, and said flaps are lifted, the glued portion B of ap adheres to and is carried by ap 5.

What I claim is:

l. A paper board carton having a closure comprising an inner or lower rectangular flap, an outer iiap covering the ilrst ap, and means sealing said flaps together along mating straight edges thereof, said aps being relatively free at the opposite mating edges, one of said aps having therein and extending completely across it between the joined and free portions a weakened line, whereby the closure may be urged in one direction to break the board along said line, so that the aps may then be opened.

2. In a carton comprising a sheet of paper board having opposed front and rear walls and coacting lateral walls; a top closure comprising an inner flap which is continuous with said rear wall, said nap having its boundary edges adjoining the top edges of the other three wallsv naps turned inwardly from said lateral walls below said inner flap, and an outer flap turned inwardly from said front wall and having a portion thereof sealingly attached to said inner ap along and adjacent said rear wall, said inner and outer flaps having relatively free portions adjacent said front wall, and said outer flap having therein and extending completely across it between the attached and free portions a weakened line, whereby on pressing the closure inwardly the outer flap may be broken along said line, so that the closure may then be opened.

3. A carton or box, one end of which is initially sealed by a closure which includes an inner rear wall flap, and an outer front wall flap, means sealing said outer iap to said inner flap along and adjacent the rear wall, said flaps being relatively free adjacent the front wall, and there being a weakened line extending completely across the outer flap between its sealed and free portions; said line defining a tongue which extends towards the rear wall; whereby when the closure is urged inwardly the weakened line may be broken so that the flaps may be opened; said inner flap having therein a tongue slit which is further from the rear wall than the point of the tongue, so that after the initial opening the flaps may be reclosed. said tongue being engageable in said slit for holding the aps in position.

4. A paper board carton, one end of which is sealed by a closure which includes an inner rear wall nap, and an outer front wall sealing nap, each of said flaps extending completely across the end; cooperating lateral wall aps disposed below the inner ilap and each extending half of the way across the end; adhesive material sealing the outer flap to the inner nap along and adjacent the rear wall, said outer and inner flaps being relatively free adjacent the front wall. and there being a weakened line extending completely across the outer iiap between the sealed and free portions: said line dei'lning a tongue which extends towards the rear wall; whereby the closure may be urged inwardly to break the sealing flap along said line, so that the aps may be opened; said inner iiap having therein a tongue slit which is further from the rear wall than the point of the tongue so that after the initial opening the naps may be reclosed, said slit being then adapted to receive said tongue for holding the flaps in position.

5. A carton comprising an end closure including an inner rear wall flap and an outer or uppermost front wall i'lap, said outeriiap having thereon a glued face, said inner ap having thereon and ext-ending along and adjacent the front wall a stippled portion whereby to prevent attachment o! the glue thereto, both aps being attached adjacent the rear wall only, and a weakened line extending completely across the outer flap between its attached and unattached portions, whereby the closure may be pressed inwardly to break the outer flap along said line, so that the flaps may then be opened.

6. A carton comprising a sheet of paper board which includes an end closure having an inner rear wall ilap and a cooperating outer or uppermost front wall flap, said outer ap having thereon a glued face. said inner ap having thereon and extending along and adjacent the front wall a stippled portion whereby to prevent attachment of the glue thereto, both flaps being attached adjacent the rear wall only, said outer nap having therein and extending completely across it between the attached and unattached portions a weakened line, said line defining a tongue which extends towards and nearly as far as the rear wall; whereby the closure may be pressed inwardly` to break the outer flap along said line, so that the iiaps may be opened; said outer flap having therein a tongue slit which is further from the rear wall than the point of the tongue so that after the initial opening the flaps may be closed. said tongue being engageable in said slit for holding the flaps in the reclosed position.
